    • 摘要: 将超细全硫化粉末橡胶(ENPs)与硫化剂硫磺或促进剂N-叔丁基-2-苯并噻唑次磺酰胺(TBBS)预先复合后再加入生胶中混炼并硫化,利用力学性能测试、NMR、DSC、DMA等方法分析了不同配方对硫化胶性能及结构的影响。实验结果表明,提前将ENPs与硫磺或TBBS复合后,可缩短起硫时间,提高交联密度,增加结合胶含量,减少Payne效应,所得硫化胶的拉伸强度、拉断伸长率、磨耗性能和抗湿滑性均好于将ENPs直接共混所得硫化胶。提前将ENPs与硫磺或TBBS复合,有利于硫磺或TBBS在橡胶中分散均匀,从而更好地发挥作用。

    • 摘要: 聚丙烯(PP)是一种无毒、无味的乳白色高结晶聚合物,其具有良好的综合性能,广泛用于包装、纺织、汽车制造等领域.但也同时具有缺口冲击强度低、成型收缩率大、耐磨性差、低温易脆断等劣势性能,这在一定程度上限制了PP的应用,因此提高PP的韧性显得尤为重要,粉末橡胶作为一种新开发的材料,在PP增韧改性研究方面具有很大潜力.对粉末橡胶增韧PP的方法、机理及研究进展进行了综述,为增强PP的韧性提供了参考,对实际应用也具有重要的指导意义.%Polypropylene (PP)is a non-toxic,tasteless milky white high-crystalline polymers,Which has a good overall performance,it is widely used in packaging,textile,automobile manufacturing and other fields.However,it also has some defects,such as low impact strength,mold shrinkage is large,poor wear resistance,low temperature brittle broken and so on,the application of polypropylene is limited,Therefore it is particularly important to improve the toughness of PP.Powder rubber as a newly developed material,it can be foreseen that powder rubber will have attracted extensive attention for toughening PP.In this paper,the toughening method and mechanism of PP modified by powder rubber were described,The advance of toughening PP in recent years was also summarized,Which provides a reference for strengthening the toughness of PP,and it also has an important guiding significance for practical application of PP.

    • 摘要: Three types of nano-CaCO3 filled powdered rubber composite particles were prepared by coagulation method using nano-CaCO3 and latices as raw materials. The influence of the content of the composite particles on the mechanical properties of polyvinyl chloride (PVC) and their different reinforcing and toughening mechanisms were investigated. TEM micrographs show that the composite particles disperse well in the PVC matrix, where the nano-CaCO3 particles exist either uncovered or embedded in the rubber continuum. It was demonstrated that all three composite particles can dramatically increase the notched impact strength of PVC, among which nano-CaCO3 filled powdered acrylonitrile-butadiene rubber (CaCO3 -NBR) can achieve high stiffness and toughness. While nano-CaCO3 filled powdered styrene-butadiene rubber (CaCO3 -SBR) improves the impact resistance at the cost of decrease in stiffness, resulting in the significantly decreasing of flexural modulus and tensile strength. The modification effect of nano-CaCO3 filled powdered carboxylated styrene-butadiene rubber (CaCO3 -X-SBR) is between CaCO3 - NBR and CaCO3 - SBR. The results also show that the compatibility between the composite particles and PVC is the key point for the reinforcing and toughening effect. The composite particles with good compatibility with PVC matrix demonstrate better synergistic reinforce and toughen effect than the ones with bad compatibility.%以纳米CaCO3浆料和丁苯胶乳、羧基丁苯胶乳、丁腈胶乳为原料,采用共凝聚法分别制备了三种纳米CaCO3-粉末橡胶复合粒子,并制备了三种纳米CaCO3-粉末橡胶/聚氯乙烯(PVC)复合材料,系统研究了复合粒子含量对PVC力学性能的影响,并探讨了复合粒子的增强增韧机制。结果表明:复合粒子在PVC树脂中分散均匀,复合粒子中的纳米CaCO3粒子以“裸露态”和橡胶“包裹态”两种形式存在于PVC基体中;三种复合粒子均能显著提高PVC的缺口冲击强度,纳米CaCO3-粉末丁腈橡胶(CaCO3-NBR)能同时起到增强增韧的效果,而纳米CaCO3-粉末丁苯橡胶(CaCO3-SBR)在提高缺口冲击强度的同时也损失了PVC原有的刚性,使其弯曲模量和拉伸强度大幅度降低,纳米CaCO3-粉末羧基丁苯橡胶(CaCO3-X—SBR)的改性效果鉴于前两者之间;复合粒子与PVC基体的相容性是影响复合粒子增强增韧改性效果的决定性因素,相容性好的复合粒子能同时起到增强增韧的效果。
